I believe the photo above also includes the sister (far right, in black), who ran a very, very suspicious "cancer charity".

So far, it seems the 'ethnicity' of the sisters has absolutely no bearing on the story/stories.

The "...and Broadwell may have had unauthorized access to classified information via her connection to Petraeus..." angle is one that must be pursued, more than the 'illicit relationships'. This, at the very top of the security establishment.

There is more to this story, lots more... and more individuals and agencies will be sucked in. The GOP also may come to regret some of its own involvement.
